Olympus CAMEDIA X-350 PT-021 - Manual (Page 32)

(6) Catching of the strap, the bag of silica gel, etc. at the time of
sealing the Case
(7) Throwing the Case from a boat into the water, jumping with the Case
into the water, or other sudden application of strong forces onto the
Case. When entering the water, hand the Case over quietly or avoid
impacts in other ways.
Q9 : What are the important points for O-ring maintenance?
A9 : Please observe the following items.
(1) Never use alcohol, thinner, benzene or similar organic solvents or
chemical detergents to clean the O-ring. When such chemicals are
used, it is to be feared that the O-ring will be damaged or that its
deterioration will be accelerated.
(2) Use the original Olympus silicone O-ring grease (white cap). The
grease attached to Cases up to PT-008 (red cap) and the grease of
other companies are not suitable for this silicone O-ring, and use of
such grease may cause deterioration of the surface and impairment
of the waterproof function.
(3) In order to avoid deformation of the O-ring when the Case is not
used for a long time, remove the O-ring from the Case, apply a thin
coat of the special grease, and store the O-ring in a clean plastic
bag. For reuse, confirm that the O-ring is free of damage and
cracks, that it has sufficient elasticity, that the surface is free of
stickiness and other abnormalities, and use it after applying a thin
coat of the special grease. Excessive application of grease does not
improve the waterproof function or the permissible withstand
pressure. However, it may facilitate attachment of sand, dirt, etc.
A thin, uniform coat produces the best result.
(4) The O-ring is a consumable product. Replace it at least once a year.
(5) Deterioration of the O-ring is accelerated by the use conditions
and the storage conditions. Replace the O-ring immediately by a
new one if it shows signs of damage, cracking or loss of elasticity.
: What are the important points for Case maintenance?
: Please observe the following items.
(1) Never use the following chemicals for cleaning, corrosion
protection, defogging, repair or other purposes.
• Never use alcohol, thinner, benzene or similar volatile organic
solvents or chemical detergents to clean the Case. Pure water or
lukewarm water is sufficient for cleaning.
• Do not use anticorrosion agents on the metal parts. The metal
parts are made of aluminum, brass or stainless steel. Cleaning
temperatures or direct sunlight may cause deformation,
discoloration or breakage of the Case and deterioration of the O-
ring. Wipe the inside of the Case with a soft cloth not causing any
fibers. Remove the O-ring, wipe off any salt, sand, dust, etc., and
also clean the O-ring groove and the O-ring contact surface in the
same way and then dry them. When an object with a sharp tip is
used to remove the O-ring from the groove, the O-ring may be
damaged and water leakage may be caused. Always use the
accessory pick for O-ring removal.
Q6 : How should I take pictures under water?
A6 : Please observe the following items for shooting under water.
(1) Fix the Case with the accessory hand strap to your wrist.
(2) When you place a finger onto the lens window, the finger will
appear in the photo. Pay attention to the position of your fingers
when holding the Case.
(3) When pressing the shutter lever, hold the Case securely with both
hands and operate the lever quietly to prevent camera shake.
(4) Look through the LCD monitor window on the rear of the Case to
confirm the picture and then press the shutter lever. Please note
that the optical viewfinder cannot be used, When the LCD
monitor is used, the battery is exhausted earlier. In order to avoid
losing shutter chances due to an exhausted battery, please always
replace a battery with a fully charged battery before each dive.
Q7 : How can I check for water leakage?
A7 : For confirmation, perform the advance test and the final test after
loading the camera. The advance test with immersing the Case
without the camera to the intended use depth to check for water
leakage is the most accurate test, but when this is difficult, it is
safer to perform this test even at a depth of 1 m or in a bathtub.
The final test also can be performed in a bathtub or a bucket.
Q8 : What are the causes for entry of water?
A8 : The main causes for the entry of water are shown below. Please
check them most carefully.
(1) Forgetting to install the O-ring
(2) The O-ring is partly or completely outside the groove.
(3) Damage, deterioration, or deformation of the O-ring
(4) Sand, fibers, hair or other foreign matter on the O-ring
(5) Sand, fibers, hair or other foreign matter on the O-ring groove or
the O-ring contact surface
